Glauber Costa 44252e421a sched/accounting, cgroups: Reuse cgroup's parent pointer 
We already have a pointer to the cgroup parent (whose data is more likely
to be in the cache than this, anyway), so there is no need to have this one
in cpuacct.

This patch makes the underlying cgroup be used instead.
